About Landsat 4 and 5
The Landsat programme is a joint USGS and NASA-led enterprise for Earth Observation that represents the world's longest running system of satellites for moderate-resolution optical remote sensing for land, coastal areas and shallow waters.
Landsat 4 was launched from Vandenberg Air Force Base in California on 16 July 1982 and the mission ended on 15 June 2001.
Landsat 5 was launched on 1 March 1984 from the same launch site, and the mission ended on 5 June 2013.

(Within a year of launch, Landsat 4 lost the use of two of its solar panels and both of its direct downlink transmitters. The downlink of data was not possible until the Tracking and Data Relay Satellite System (TDRSS) became operational). In 1987 the TM instrument was switched off.

Landsat 4 and 5 are part of ESA's Third Party Missions Programme, in which ESA has an agreement to distribute data products from the missions.
Landsat 4 and 5 Objectives
Landsat's Global Survey Mission is to image repetitively Earth's land and coastal areas with the aim of monitoring changes to those areas over time.

Landsat 4 and 5 Data
Download data from Landsat-4 and 5 datasets through the ESA Landsat Online Dissemination System.
ESA offers registered users access through the Online Dissemination server to the following data collections:
- Landsat 5 Thematic Mapper Geolocated Terrain Corrected Systematic processing (LANDSAT.TM.GTC): Landsat 5 TM ortho-rectified Level 1T dataset acquired by ESA stations
- Landsat MSS ESA archive: Landsat 1 to 5 MSS Level 1 GEO (geometrically corrected, L1G) and GTC (geometrically and terrain corrected, L1T) products acquired by ESA stations
Landsat 5 data can be visualised through the HEDAVI (HEritage DAta Visualisation) service. HEDAVI allows you to discover a wealth of heritage data from ERS and Envisat missions, as well as from Landsat 5 and 7, two important heritage Third Party Missions, through ESA's Long Term Data Preservation programme.
